XIV. 320/2 In a problem of this kind the paleoecologist is greatly handicapped by the fact that every criterion available is susceptible of a variety of interpretations. 1954Jrnl. Geol. LXII. 234/2 Paleoecological factors, such as wide fluctuations in salinity and insolation-induced temperatures, are insufficient for such mean growth temperatures. 1959Jrnl. Palæont. XXXIII. 936/1 More in need of emphasis paleoecologically, the change from water to sediment or between sediment layers may be almost as profound as that from air to water. 1961Webster, Paleoecologic. 1963Potter & Pettijohn Paleocurrents & Basin Anal. i. 2 Knowledge of current direction is also useful in paleoecologic studies. 1975Nature 6 Feb. 400/1 Palaeoecological studies suggest that the species [sc. Armeria maritima] was widespread in distribution during the cold and disturbed conditions at the close of the last glaciation. 1977A.
